I'm told by Leon that REW (3rd gen) engines are designed to run at around 205 - 210F. He advised not taking the engine above 240 except for short duration, and that oil temps should never regularly go over 250. 266 would be his limit on a really hot day, and only for a short time. I'm really concerned about the evap core in the current installation. From what you say, I would be too. Didn't a rotary airplane have two (count 'em) engine fires because of burst aftermarket oil coolers. If memory serves the owners wife made him sell the rotary and install a Lycoming. Sticking with a stock cooler seems safest. John (ready to fly.
